I wonder whether those "shaders" should be considered as purely
functional in nature, and thus not copyrightable: I seem to recall that
there's U.S. case law about a functionality exception to copyright
protection, and the following was stated:

which seems to suggest that those "shaders" are necessary to comply to
a software standard (namely, the RenderMan interface standard defined
by Pixar Animation Studios).

Maybe a lawyer should be consulted about this issue...
